集成 WalletConnectSwiftV2 按照官方文档就可以(github.com/WalletConne... WalletConnect Inc 现已更名为 Reown。作为此次过渡的一部分，我们将弃用我们支持的平台上的大量存储库/软件包，并过渡到 Reown 组织下发布的等效版本。 此存储库现已被视为已弃用，并将于 2025 年 2 月 17 日终止使用。有关更多详细信息（包括迁移指南），请参阅：docs.reown.com/advanced/wa...),
WalletConnectSwiftV2(reown-swift)是用swift实现的,所有项目用swift会方便很多 git库 github.com/WalletConne...改为github.com/reown-com/r...
pod WalletConnectSwiftV2
但有些依赖库会缺少, 需要单独pod 如:
pod 'WalletConnectSwiftV2/Web3Wallet', '1.6.6' pod 'WalletConnectSwiftV2/WalletConnectRouter', '1.6.6' pod 'WalletConnectSwiftV2/WalletConnectIdentity', '1.6.6'
dapp使用
创建DappConnect.swift 实现回调方法
swift
@objc protocol DappConnectDelegate {
@objc func dappWalletList(_ succeed:Bool,_ type:Int)
@objc func dappSelectConnect()
@objc func failedToConnect()
@objc func didConnect(_ dict:NSDictionary)
@objc func didDisconnect()
@objc func didUpdate(_ dict:NSDictionary)
}
swift
@objc public func start() {
var isDapp = true
//创建AppMetadata对象
let metadata = AppMetadata(
name: ExName,
description: ExName,
url: String(format: "https://www.%@/favicon.ico", DomainSwithTool.currentDomain()),
icons: [String(format: "https://www.%@/favicon.ico", DomainSwithTool.currentDomain())]
)
Pair.configure(metadata: metadata)
#if DEBUG
if CommandLine.arguments.contains("-cleanInstall") {
try? Sign.instance.cleanup()
}
#endif
//已断链回调
Sign.instance.sessionDeletePublisher
.receive(on: DispatchQueue.main)
.sink { [unowned self] (topic, reason) in
//self.delegate.didDisconnect()
}.store(in: &publishers)
//返回数据回调
Sign.instance.sessionResponsePublisher
.receive(on: DispatchQueue.main)
.sink { [unowned self] response in
presentResponse(for: response)
}.store(in: &publishers)
//地址(address)/链(chainId)变更回调
Sign.instance.sessionUpdatePublisher
.receive(on: DispatchQueue.main)
.sink { [unowned self] (topic, namespaces) in
onSessionUpdateNamespaces(topic, namespaces)
}.store(in: &publishers)
//连接成功返回支账户信息(链,方法名称,地址0x)
Sign.instance.sessionSettlePublisher
.receive(on: DispatchQueue.main)
.sink { [unowned self] session in
if isDapp{
isDapp = false
showAccountsScreen(session,false)
}
}.store(in: &publishers)
}获取所有支持钱包列表
swift
func getListings() async throws -> [Listing] {
let httpClient = HTTPNetworkClient(host: "explorer-api.walletconnect.com")
let response = try await httpClient.request(
ListingsResponse.self,
at: ExplorerAPI.getListings(
projectId: Web3Modal.config.projectId,
metadata: Web3Modal.config.metadata
)
)
return response.listings.values.compactMap { $0 }
}获取某个钱包logo url
swift
private func imageURL(for wallet: Listing?) -> URL? {
guard let wallet else { return nil }
// case small = "sm" case medium = "md" case large = "lg"
let urlString = "https://explorer-api.walletconnect.com/v3/logo/\("md")/\(wallet.imageId)?projectId=\(InputConfig.projectId)"
return URL(string: urlString)
}Listing 类型转 WalletModel类型
swift
self.walletList.removeAll()
for wallet:Listing in self.wallets!{
let model:WalletModel = WalletModel()
model.id = wallet.id
model.name = wallet.name
model.homepage = wallet.homepage
model.order = wallet.order ?? 0
model.imageId = wallet.imageId
model.app.ios = wallet.app.ios ?? ""
model.app.mac = wallet.app.mac ?? ""
model.app.safari = wallet.app.safari ?? ""
model.mobile.native = wallet.mobile.native ?? ""
model.mobile.universal = wallet.mobile.universal ?? ""
model.imageUrl = imageURL(for: wallet)!
self.walletList .append(model)
}连接钱包
swift
@objc func connect() {
let chain = String(format: "eip155:%@",WalletNodeManager.shared().currentNode.chainID)
let namespaces: [String: ProposalNamespace] = [
"eip155": ProposalNamespace(

self.deeplinkUri = "\(uri!.deeplinkUri)"
delegate.dappSelectConnect()
